1Product Introduction
LH-D6901Online conventional 5-parameter detectorIt is an intelligent online controller widely used in water quality testing in sewage treatment plants, waterworks, water stations, surface water and other fields, as well as in process areas such as electronics, electroplating, printing and dyeing, chemistry, food, pharmaceuticals, etc., to meet the needs of water quality testing; Adopting digital and modular design, different functions are completed by various unique modules, with built-in recognition of more than thirty types of digital electrodes that can be combined arbitrarily, and reserved with * expansion function.
IIOnline conventional 5-parameter detectorProduct Features
1. Support simultaneous access to 4 sensors.
2. Can be connected to composite sensors, supporting real-time information with multiple parameters, and displaying up to 4 sub parameters.
3. Intelligent operation: High definition color touch screen, 78x78CTP touch ultra clear screen, easy to operate interface, clear results at a glance.
4. Strong scalability and practicality: Supports over 30 types of sensors.
5. Multiple output modes: Supports Modbus, 4-20mA, JSON format data communication.
6. Relay delay function: Supports customers to use with electric ball valves to achieve water inlet control or automatic drainage function.
7. High and low point alarm function.
8. Data monitoring: Record historical data, including historical data, alarm records, operation logs, real-time curves, and other content.
9. middle/English language switching.
